Different game, different mechanic
NumberFlow is a number-path-sum puzzle: you connect one continuous path through adjacent grid cells so the printed digits add up to a target. It has no row, column or box fill rule, no Latin-square constraint, and no arithmetic-cage rules; its branding, naming, color scheme and share format are its own. Any resemblance is limited to the broad “number puzzle” and “daily puzzle” formats, which are genres rather than any one product.
How puzzles are made
Each daily puzzle is produced by a deterministic algorithm seeded from the calendar date (UTC) and validated to have exactly one solution. Puzzles are not generated by an artificial-intelligence or large-language model, and they are not downloaded from a server — your browser computes the same puzzle everyone else gets that day.
